Error because class B inherits A but variable x isn't inherited

Error because when object is created, argument must be passed like Derived_Test(1)

Error, the syntax of the invoking method is wrong

The program runs fine but nothing is printed

What will be the output of the following Python code? class A: def __init__(self): self.__x = 1 class B(A): def display(self): print(self.__x) def main(): obj = B() obj.display() main()

Error, invalid syntax for object declaration

What will be the output of the following Python code? class A: def __init__(self): self._x = 5 class B(A): def display(self): print(self._x) def main(): obj = B() obj.display() main()

What will be the output of the following Python code? class A: def __init__(self,x=3): self._x = x class B(A): def __init__(self): super().__init__(5) def display(self): print(self._x) def main(): obj = B() obj.display() main()

Error, class member x has two values

Error, protected class member can't be accessed in a subclass

What will be the output of the following Python code? class A: def test1(self): print(' test of A called ') class B(A): def test(self): print(' test of B called ') class C(A): def test(self): print(' test of C called ') class D(B,C): def test2(self): print(' test of D called ') obj=D() obj.test()

test of B called test of C called

test of C called test of B called

Error, both the classes from which D derives has same method test()

What will be the output of the following Python code? class A: def test(self): print("test of A called") class B(A): def test(self): print("test of B called") super().test() class C(A): def test(self): print("test of C called") super().test() class D(B,C): def test2(self): print("test of D called") obj=D() obj.test()
